Vedic Astrology Apps Compared: Rohshan vs Co-Star vs AstroTalk

TL;DR: These three apps solve different problems. Co-Star is a Western (tropical) app built for casual, social daily horoscopes. AstroTalk is a marketplace for talking to a live human astrologer, billed by the minute. Rohshan casts your full Vedic (sidereal) chart for free and turns it into clear guidance, with simple per-reading pricing instead of a per-minute meter or a subscription. If you want to actually understand your Vedic chart — and keep it — Rohshan is built for that. Want social Western horoscopes? Choose Co-Star. Want a live human conversation? Choose AstroTalk.

The short answer

• Choose Co-Star if you want a slick, social, Western daily horoscope to share with friends.
• Choose AstroTalk if you specifically want to talk to a live human astrologer and don’t mind paying by the minute.
• Choose Rohshan if you want an accurate Vedic birth chart — every divisional chart, dasha, yoga and panchanga — free to cast, explained clearly, and yours to keep.
• Free kundli websites are fine for a quick chart, but tend to be cluttered with ads and shallow on interpretation.

The one difference that matters most: Western vs Vedic

Co-Star uses the tropical (Western) zodiac. Rohshan and AstroTalk use the sidereal (Vedic) zodiac, which is tied to the actual constellations. The two systems have drifted about one sign apart, so your Co-Star Sun sign is often a different sign in a Vedic chart.

If you specifically want Vedic astrology — a proper kundli, your nakshatra, your dashas — a Western app is answering a different question. (New to the difference? See our guide on how to read your Vedic birth chart, or find your nakshatra free.)

How each one works — and what you pay

Co-Star — social Western horoscopes (freemium)

Co-Star generates a natal chart from real astronomical data and uses AI, with some human writing, to deliver short daily horoscopes. Its standout is social: comparing charts with friends. It’s free to download, with deeper features behind a paywall. It’s a great casual on-ramp — but interpretation stays surface-level, and it’s Western rather than Vedic.

AstroTalk — live human astrologers (pay-per-minute)

AstroTalk is a marketplace that connects you to thousands of real astrologers for live chat, call or video. Consultations are human-driven, which many people value for empathy and for asking about a specific worry. You pay per minute from a prepaid wallet, with rates that vary by astrologer, usually after a short free first session — plus optional paid reports and a store of spiritual products. It’s excellent when you want to talk to a person; the trade-off is that the per-minute meter adds up, and quality depends on which consultant you pick.

Rohshan — your full Vedic chart, free to cast (pay per reading)

Rohshan computes a complete sidereal Vedic chart — Lagna, nakshatras, every divisional chart, dashas, yogas and panchanga — with no cost and no sign-up to cast it. When you want those calculations turned into clear, personal guidance, you pay per reading: a simple credit, not a per-minute timer and not a recurring subscription. The chart and your readings are yours to keep. It’s built for people who want to genuinely understand their chart — seekers, learners and practitioners alike — with a transparent, published calculation method.

Free kundli sites — quick charts, heavy ads

The popular free-kundli portals will generate a chart at no cost, but the experience is usually ad-heavy and cluttered, with shallow auto-interpretation and constant report upsells.

Side-by-side comparison

Which should you choose?

New, curious, or social? Co-Star is the friendliest on-ramp — just know it’s Western, not Vedic, and the interpretation stays surface-level.

Want to talk to a human about a specific question — marriage, career, timing? AstroTalk’s live astrologers are exactly the point. Budget for the per-minute cost and pick a well-rated consultant.

Want the actual Vedic depth — and to own it? Rohshan gives you the full sidereal chart free, then clear per-question guidance you keep forever, with a transparent calculation method. No per-minute meter, no subscription treadmill.

Frequently asked questions

Is Co-Star Vedic or Western astrology? Co-Star uses the tropical (Western) zodiac. For Vedic (sidereal) astrology — kundli, nakshatras, dashas — you’ll want a Vedic tool such as Rohshan.

Is there a free alternative to AstroTalk? AstroTalk’s value is live human consultation, billed per minute. If you mainly want an accurate Vedic chart and clear guidance without a per-minute meter, Rohshan casts your full chart free and prices written guidance per reading.

What is the best free Vedic astrology app? It depends on what you want. For a genuinely in-depth sidereal chart you can cast free and keep — with divisional charts, dashas and yogas — Rohshan is built for exactly that. Free kundli portals also produce charts, but tend to be ad-heavy and shallow on interpretation.

Does Rohshan charge per minute like AstroTalk? No. There’s no per-minute timer and no subscription. Casting your chart is free; you pay a simple per-reading credit only when you want written guidance, and it’s yours to keep.

Can I use Co-Star for Vedic astrology? Not really — it’s a Western app, so your placements follow the tropical zodiac, which usually differs from your Vedic chart by about one sign.
